方法详细资料

• setFlashMapTimeout

  public void setFlashMapTimeout​(int flashMapTimeout)

  Set the amount of time in seconds after a FlashMap is saved (at request completion) and before it expires.

  The default value is 180 seconds.

• getFlashMapTimeout

  public int getFlashMapTimeout()

  Return the amount of time in seconds before a FlashMap expires.

• setUrlPathHelper

  public void setUrlPathHelper​(UrlPathHelper urlPathHelper)

  Set the UrlPathHelper to use to match FlashMap instances to requests.

• getUrlPathHelper

  public UrlPathHelper getUrlPathHelper()

  Return the UrlPathHelper implementation to use.

• retrieveAndUpdate

  public final FlashMap retrieveAndUpdate​(HttpServletRequest request,
                                          HttpServletResponse response)

  从接口复制的说明: FlashMapManager
  Find a FlashMap saved by a previous request that matches to the current request, remove it from underlying storage, and also remove other expired FlashMap instances.

  This method is invoked in the beginning of every request in contrast to FlashMapManager.saveOutputFlashMap(org.springframework.web.servlet.FlashMap, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse), which is invoked only when there are flash attributes to be saved - i.e. before a redirect.

  指定者:

  retrieveAndUpdate 在接口中 FlashMapManager

  参数:

  request - the current request

  response - the current response

  返回:

  a FlashMap matching the current request or null

• isFlashMapForRequest

  protected boolean isFlashMapForRequest​(FlashMap flashMap,
                                         HttpServletRequest request)

  Whether the given FlashMap matches the current request. Uses the expected request path and query parameters saved in the FlashMap.

• saveOutputFlashMap

  public final void saveOutputFlashMap​(FlashMap flashMap,
                                       HttpServletRequest request,
                                       HttpServletResponse response)

  从接口复制的说明: FlashMapManager
  Save the given FlashMap, in some underlying storage and set the start of its expiration period.

  NOTE: Invoke this method prior to a redirect in order to allow saving the FlashMap in the HTTP session or in a response cookie before the response is committed.

  指定者:

  saveOutputFlashMap 在接口中 FlashMapManager

  参数:

  flashMap - the FlashMap to save

  request - the current request

  response - the current response

• retrieveFlashMaps

  protected abstract List<FlashMap> retrieveFlashMaps​(HttpServletRequest request)

  Retrieve saved FlashMap instances from the underlying storage.

  参数:

  request - the current request

  返回:

  a List with FlashMap instances, or null if none found

• updateFlashMaps

  protected abstract void updateFlashMaps​(List<FlashMap> flashMaps,
                                          HttpServletRequest request,
                                          HttpServletResponse response)

  Update the FlashMap instances in the underlying storage.

  参数:

  flashMaps - a (potentially empty) list of FlashMap instances to save

  request - the current request

  response - the current response

• getFlashMapsMutex

  protected Object getFlashMapsMutex​(HttpServletRequest request)

  Obtain a mutex for modifying the FlashMap List as handled by retrieveFlashMaps(javax.servlet.http.HttpServletRequest) and updateFlashMaps(java.util.List<org.springframework.web.servlet.FlashMap>, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse),

  The default implementation returns a shared static mutex. Subclasses are encouraged to return a more specific mutex, or null to indicate that no synchronization is necessary.

  参数:

  request - the current request

  返回:

  the mutex to use (may be null if none applicable)
